llie ..in.-"l'riietion and operation of my machine will he more readily understood if prelaeed by an explanation of the envelop \vliieh the niaehine is designed to make, al-

l`though it is to he understood that the inl .'eiitinn ia applieable. to the inannfaetnreof other Vtin'inr.- of envelop and that I .have illustrated only one embodimenty of my iny .'enl'ion A The envelop, as illustrated in Figs. 29 and 30, consists of a front .A or body having on its npper edge a Closing flap B, that has the nsnal strip ot adhesive. b; the front A also haring side flaps tl., which are narrow and i whieh are provided on their backs with adlieeive e. which adhesive may extend along llie side edgee ol the hack of lne envelop.

At the lower edge of the front A', the back D of the envelop is formed. As illustrated in Fig. 30, the back D is secured by the adhesive c to the side flaps C.

The steps of vforming the envelop from the strip of material are illustrated in Figs. T8 and 2S, The first operation is -the cutling or the scoring of the strip E preparatory to removing the pieces e, whose removal results in the formation of the side edges of the closing flap, of the side edges of the front or body of the envelop, and of the side edges of the back of the envelop. The next step is the removal of the pieces e, as illustrated at e', which step is followed by the formation of creases c2 between the side flaps and the body of the envelop. 'lhe side fiaps are then folded over on the body of the strip, 'as at e3, after which the adhesive c is applied to the side flaps. This is followed by the application of the adhesive b for the closing flap of the envelop. The crease c4 between the front and back of the envelop is then formed and the back is bent over preparatory to being secured to the side flaps. The score e,b along the top edge of the closing flap, is then made and the crease e between the front of the envelop and the closing flap is made, the formation of the said crease drawing the back of the envelop away from the body of the strip and causing the separation of the blank from the body of the strip along the score e5.

In carrying my invention into practice7 l provide a frame 1 of any desired construction. In the illustrated embodiment of my invention such vtrame consists of side frames 2, composed chiefly of vertical and horizontal bars cast in one piece, such side frames being connected by the various shafts of the machine, and also, if desired, by braces. 'T he rod 4 is screw-threaded ard opposing cones G are mounted thereon, the roll being seated on the said cones. The position of the roll can thus be adjusted laterally along the rod. The strip E passes from the roll around a rod 7 that lies upon the upper surface of the roll and rests against the forwardl y and upwardly inclined edges of the plates- S 4secured to the frame. 'l'he rod 7 hasa collar 8 topi-event its lateral displacement, and it is provided with a disk or col.- larl) that is adapted to bear against and guide one edge of the strip E, and also with an opposing disk or collar 10 that is yieldingly forced against the end of the rolland the edge of the paper by a spring 1l mounted on the said rod. lhe paper is t braked 7 by the sharp turn `xround the rod T so that it do xs not unwind too freely. ttor 'passing around vthe rod T, the strip lil passes under a roller l2 and then passes over a barda-red roller 1?, against which operate ruiter rolls 111.

The rollers 1t", and 14 are illustrated in ,are

detail in Figs. 9 and 10. Each cutter roll 14 is composite and consists of a cylindrical body 15, having two diagonal slots. 16 formed therein, in each of which is mounted a knife 17, the latter being secured in their slots by setscrews 1S. Against the inner face of thel body 15, a disk 1S) is clamped by a nut 20. The disk l9l has formed onit a blunt cutting edge, and of a configuration corresponding to the line illustrated in Fig. 11 from the point 21 to the point 22. The oblique lines from the points 21 and to the edges of the paper are cut by the knives 17. The shaft 23 of the rolls lei is mounted in boxes 2li that are vertically movable in a bracket 25 mounted on a frame of the machine. .Springs 26 are placed beneath the boxes to counter-balance the weight of the shaft and the rollers. On the upper ends of the boxes 24, strips or pieces of rubber 27 are placed and hand screws 28 be'ar on the said rubber or other yielding material or upon metal washers or disks seated thereon so that the cutting rolls are yield` ingly pressed against the hardened roll 13. The action of the cut-ting rolls as thus constructed l have found in practice to be very advantageous. The rubber washers allow the cutting rolls to yield sufficiently so that the knives are not injured by running. on the hardened roll, and I have found that they will last for a longitime without sharpening. The springs beneath the boxes prevent the weight of the shaft and rollers from forcing the knives too hard against the hardened roller, and thus from causing any injury.

After being scored as illustrated in Fig. 11, the strip passes over rollersl 29 which are provided with devices for removing the scored portions e of the strip. (See Figs. 12 to 41G.) The rollers 29 are preferably faced with emery cloth, or izther roughened ,y

material, so that the paper will not slip upon the said rollers. Ait the outer side of each roller 29 a finger 30 is piroted in a slot in the shaft 31 of said rollers, upon a pin 32, so that the said finger can over-lie the portion of the roller 29 which is occfr-:l by the portions e that are to 'be removed from the strip E. The fingers 3 0 are 'moved over to clamp the scored portions c by a sta-l tionary cam 32 which is formed'on a sleeve 33, the latter being secured by a screw 34 in a bracket'. The bracket 35 also embraces the shaft of the hardened roll 13, vso that the cam 32 is prevented from rotating with the shaft 31. The finger 30 is held against the cam by a spring-pressed bolt 34 mounted in the roller 2f). In order that the fingers and rollers 2) may be adjusted for different widths of envelope, the pins 32 areI mounted in grooves in the shaft 31, and the blocks 36 are secured 1n ad] usted osition by screws 37. The action of the ngers ZO is illustrated in Figs. 14, l5 and 16. As the fingers pass above the level of the strip as illustratedzin Fig. ,14, theyv are forced over to` clamp the scoredportions e against the rollers 29, and are held in this position as rotatel to the position illustrated in thus carrying the scored portions e guides as securedt'o a bar 139 that is secured toy hebra klets of the bearing lof the shaft foii'thfe rol, ers 14. 4The cams 32 can be just'ed circumferentially in the brackets 35. Collars 33` may be placed back of the yeey/*e553 toprcvent their yielding or spreadi The. strip next passes to the mechau1u for creasing the side liaps of the envelop.4 Such mechanism is illustrated indetail Figs'2,l 17,18 and 19. It consists es- -sentitilly vof late 40 having ,adjustable be tingel41h1ipon itin jvhich is mounted a sh ,42 Vthat; ca'ir`ies"creasing disks 43. The cr a `iig `d slis are driven by a roller 44 that contacts with the upper surface of the strip Eytheroller 44 preferably having emery cloth or other form of rough material on its face, so 'that it will be driven by the paper. In. order` more eHectively to form the creases, the disks 43 run in grooves 44. ln

to preventhe inked surface of the paper in case it should 4be printed from com- 1r\1g4 ilu-contact with the plate 40, the grooves 44 are formed in plates 45 that only extend luider the ,paper a short distance inside of the creasing lines as illustrated in. Fig. 1T.

The-plates 45 are laterally adjustable, ow-

ing to their beingsecured to the plates 40 by screws 46 passing through slots in the 'saidplates.. After being creased, Ithe side ,fiapsC pass under folding plates-47`v which have warped surfacesi 48 that bend over the flapsl C. Beyond the'plate 40 is a roller 49 which yserves an impression f-froller for type-.disks '50. thatip'int theV strips of adhesivecyupon 'the side flaps C oftiie envelop. Thedisks .50 are mounted on slilafts 51 hav! ing'g'bearingr inthe side walls of paste cupsv v52the `latter being .formed on'the upper endsof arms 53 that are `forked to straddle .*the.cl1iving shaft 54 of the machine. Rollersr()a are mounted on the shafts 51 to be -periodically struck by cams 50b on the shaft off-the-` roller 49 `and thusthe'disks 50 are raised/awayffrom Vthe paper when they come to. .thefclosing flap of the envelop. The shafts 5 1 are provided with gears that-*f A and the belt mesh with `gears 56 on the shaft of the roller 49. 'The paste-applying portions iof the disks 50 rotate at the same speed as the speed of the strip E. Springs 57 ser. t.; keep the disks 50 up to their work. VThe driving shaft is provided with a driving drum 58 whose face is preferably covered with emery cloth or is roughened Ain any other manner. A preferably soft belt 59 passes over the roller 49, around and under the driving drum 58 and around a guide roller 60 on the rear side of the driving drum, from whence the belt passes around a lower guide roller 61 and over a small roller 62 in front of the driving drum and thence back to the roller 49. The roller 49 is preferably suiiiciently above the driving drum so that the belt 59 does notcontact with the driving drum at this point, thus forming a Haring opening into which the end of the strip E can find easy entrance. I

have found that the strip is gripped between the rough face of the driving drum 59 so firmly that the strip E can be driven to the point where the blanks are severed without any other feeding means. The forked ends of the arms 53 are received in grooves in collars 63 that are adjustable-along the shaft 54 for making envelops of different widths.

For convenience in making envelops of different widths, l prefer to form the roller in three parts: a central part 49a of re# duced diameter for the belt 59, and end sections 49b of full diameter that can be adjusted along their shaft. Thev gumming disks act against the paper that isover the ,i

hard surface of the sections 49. From the driving druin,.a strip E of paper passes between an upper roller 64 and a lower roller 65. the upper roller having a type 66 `by which the strip of adhesive his applied to the closing strip of the envelop. The type HG extends through the full circumference of the roller 64, and the roller 64 is raised away from the paper while the body ofthe envelop passes under it, by a earn 64, which acts on the lever- 64 in which the bearings of the Toller 64 are formed.l The lever 64b may be4 depressed a spring' 64"'. The

cam 641`is mounted upon the 'shaft of the roller The roller 64 is continuously driven,Y by gear i64 meshing with gear 64e on shaft of the roller 65. In order to insure that the strip E will leave thelriving drum 'and not wind itself around it, the driving= drum is provided with a groove (i7 in which runs an endless cord 68,'which latter 'also' passes around a grooved pulley or roller 70, that is mounted on a shaft 71, the pulley 70 being conveniently mounted over the idle roller 60 of the belt 59. The strip E is thus removed from the driving drum and carried well along with the felt belt before it is out ofcontrolofthescordS. Adhesive is ap- AST and 8S. The roller ST has ereasing;

The action o1 the creasing" blades is to 'torni the top and bottoni creases" and e of the envelop. Their action illustrated in detail in Figs. 24 to 2T.

The belts 10S pass orer a pulley 103 and thence pass under the pulley and l'iorizontally rea-rward and around and thence forward and around an upper `pulley 10S, thence rearward and unoer a- `than the' strip ot' paper E, and thus the envelops are crowded together, over-lapping each other, as illustrated in Fig. 27. enrelops are rarried by the belts 105 under the pulleys 100 and 107, and up over a pair of round belts 115 that run around pulleys 11G and 11T and enter slots in a plat-e 11S.

The belts 10.3' deposit the envelops upon the 10o belts 115, and the latter carry them up ,and deposit thein upon the inclined plate 11S. The enrelops are taken by hand from the plate 11S and counted and put up lin bundles on the table 119. t'laps oit the envelops oit' an ent-ire bundle over together at a single operation instead of folding ea eh one over on its own envelop, since the tlaps oil' the entire bundle can be opened by a. single nioreiuent ready to putin the contents. ln order to raise and lower the round belts so as to adjust their relation to the belts 105 Jto-enable the envelops' lo be deposited inost. etlieiently on the belts tlf, l mount the shat't of the pulley 116 in 115 levers being bell-eranlelerers 120, such mounted upon the shaft 121 of the'p'ulley 10T by downwardly opening slots formed in the said levers. 'lhe levers `120 are oonneeted for strength by a bolt 122. The horizontal arms ont the levers 120 rest on a crossbar 12?) earried by the arms 124 O belleranks that are pivoted upon bolts 125 on the traine. The levers 121 each have an arcshaped slot 1127, that serves to clamp the bell-cranks in any desired position.

The various parts of the machine are driven by the following mea-ns: Power is applied tothe shalt ot' the roller. 49, and '130 100 that is beneath inst a The cords 'S0 ay second llarge pulley 107, 85

The roller 14 is driven from the shaft of the roller 13 by a pinion 134. The shaft of the roller 13 carries a gear 135 that meshes with an idler 136, which meshes with a gear 137 on the shaft 31. The shaft of the roller carries the pinion 138 that meshes with the gear 128. Such shaft also carries a belt-pulley 139 Whose round belt runs over a pulley 140 on the shaft 141, that carries the pulleys 104 by vvhich belts 101 are driven. The shaft has a sprocket-wheel 144 "Whose chain 145 drives a `sprocket-Wheel 146, the latter being connected with a gear 147. The gear 147 ldrives a gear 148lthat is keyed on the shaft of the roller 65, which shaft also has a pinion`149 that meshes Wi th the-pinion 150 to drivcrthe roller 74, lThe shaft 65 has a pinion 64a that meshes `with a gear 641 -on the shaft ofthe roller 64.*` A pinion 152 is fastened to the gear 147 and drives the roller 79'by a pinion 153 which, in turn, drives the roller 78 by a gear 154. The gear 152 also drives the roller 88 by a gear 155, which latter gear meshes with a gear 156 On the shaft of the roller 87. The gear 155 also drives the shaft of the roller 97 and cams 95 by aV gear 1565i.` The gear 156a meshes with gear 157, carrying a gear 157g, meshing With a ygear 158 on the shaft of the pulley 117, and the gear 158 meshes With a gea-r 159 on the shaft of the pulley 108. A

The operation ofl my machine has been stated as the construction has been eX- plained. It may, however, be summarized as follows :fThest-rip of paper first passes between the rollers 1 3 and 14, and a scoring is made preparatory tothe removal of the pieces. These vpieces arethen removed by fingers 30 and rollers 29 and the side creases of the envelopA are made by the creasing over by the Warped plates 47; vthe lines of adhesive c are/then lapplied to the side-liaps C by the disks 50, and the strip passes around the driving drum and between the rollers 64 and 65 Where, the adhesive b is applied to the closing flaps. The scoring e5 to form the top edgey of the closing fiap is next made by the rollers 78 1and 79, and the bottom crease is then made by the blade 89. The back of the lenvelop is then folded by the blade 92.y The top crease of the envelop is then formed by the blade 90, and the blank is severed from the strip E. At the same time the back of the envelop is secured 65 to the side aps C, and tlieenvelop is dedisks 43. Tlie'fside flaps C areA then folded' livered by cords 99 and cords 101 between the belts 105 and the pulley 106. The belts 105 operating with pulleys 106 and 107, deliver the completed envelop upon the round belts 115, and they, in turn, deliver them upon the inclined plate 118. The envelops are then 4 separated by hand into proper quantities to form a bundle. and all of the flaps of a single bundle are turned down atone time von the back of the last envelop of the bundle, and they are secured as by a band for sale.

It is obvious that various changes can be made in the above embodiment of my invention which Will be within the spirit of my invention.
